public Canonicalizer20010315(boolean includeComments)

Constructor Canonicalizer20010315

Parameters:

includeComments -

Method Details

engineCanonicalizeXPathNodeSet

public byte[] engineCanonicalizeXPathNodeSet(java.util.Set<org.w3c.dom.Node> xpathNodeSet, java.lang.String inclusiveNamespaces) throws CanonicalizationException

Always throws a CanonicalizationException because this is inclusive c14n.

Specified by:

engineCanonicalizeXPathNodeSet in class CanonicalizerSpi

Parameters:

xpathNodeSet -

inclusiveNamespaces -

Returns:

none it always fails

Throws:

CanonicalizationException - always

engineCanonicalizeSubTree

public byte[] engineCanonicalizeSubTree(org.w3c.dom.Node rootNode, java.lang.String inclusiveNamespaces) throws CanonicalizationException

Always throws a CanonicalizationException because this is inclusive c14n.

Specified by:

engineCanonicalizeSubTree in class CanonicalizerSpi

Parameters:

rootNode -

inclusiveNamespaces -

Returns:

none it always fails

Throws:

CanonicalizationException

engineCanonicalizeSubTree

public byte[] engineCanonicalizeSubTree(org.w3c.dom.Node rootNode, java.lang.String inclusiveNamespaces, boolean propagateDefaultNamespace) throws CanonicalizationException

Always throws a CanonicalizationException because this is inclusive c14n.

Specified by:

engineCanonicalizeSubTree in class CanonicalizerSpi

Parameters:

rootNode -

inclusiveNamespaces -

propagateDefaultNamespace - If true the default namespace will be propagated to the c14n-ized root element

Returns:

none it always fails

Throws:

CanonicalizationException

handleAttributesSubtree

protected java.util.Iterator<org.w3c.dom.Attr> handleAttributesSubtree(org.w3c.dom.Element element, NameSpaceSymbTable ns) throws CanonicalizationException

Returns the Attr[]s to be output for the given element.
The code of this method is a copy of handleAttributes(Element, NameSpaceSymbTable), whereas it takes into account that subtree-c14n is -- well -- subtree-based. So if the element in question isRoot of c14n, it's parent is not in the node set, as well as all other ancestors.

Parameters:

element -

ns -

Returns:

the Attr[]s to be output

Throws:

CanonicalizationException

handleAttributes

protected java.util.Iterator<org.w3c.dom.Attr> handleAttributes(org.w3c.dom.Element element, NameSpaceSymbTable ns) throws CanonicalizationException

Returns the Attr[]s to be output for the given element.
IMPORTANT: This method expects to work on a modified DOM tree, i.e. a DOM which has been prepared using XMLUtils.circumventBug2650( org.w3c.dom.Document).

Parameters:

element -

ns -

Returns:

the Attr[]s to be output

Throws:

CanonicalizationException

circumventBugIfNeeded

protected void circumventBugIfNeeded(XMLSignatureInput input) throws CanonicalizationException, javax.xml.parsers.ParserConfigurationException, java.io.IOException, org.xml.sax.SAXException

Throws:

CanonicalizationException

javax.xml.parsers.ParserConfigurationException

java.io.IOException

org.xml.sax.SAXException

handleParent

protected void handleParent(org.w3c.dom.Element e, NameSpaceSymbTable ns)

Overrides:

handleParent in class CanonicalizerBase
